Study Notes
The Integumentary System
- The protective covering of the body, consisting of skin, hair, hooves, claws, horns, and feathers.
- Functions:
- Physical protection
- Prevention of dehydration
- Body temperature regulation
- Provides sensory information through touch
- Metabolic activity (Vitamin D production)
- Waste excretion (sweat)
The Skin
- The largest organ of the body
- Composed of three layers:
- Epidermis (outermost, avascular layer)
- Dermis (corium, layer with blood vessels)
- Subcutaneous layer (hypodermis, composed of adipose tissue)
Epidermis
- The outermost layer of skin
- Composed of 5 layers:
- Stratum basale
- Stratum spinosum
- Stratum granulosum
- Stratum lucidum
- Stratum corneum
Dermis
- The layer directly deep to the epidermis
- Also called the corium
- Layer where blood vessels start to be found after incision
Hypodermis
- Located deep to or under the dermis
- Composed primarily of adipose tissue
- Having fewer blood vessels means that medication injected subcutaneously is absorbed more slowly
Associated Structures
- Glands:
- Sebaceous glands (produce sebum for lubrication of the skin)
- Sweat glands (secrete watery fluid containing salts and waste products)
- Hair:
- Covers almost the entire surface of the body of most domestic animals
- Variations include whiskers, mane, switch, mohair, cashmere, wool, and feathers
- Beaks/bills:
- Projecting mouthpart of birds
- Feathers:
- Body covering of avian species
- Two basic types: vaned feathers and down feathers
- Horns:
- One of the usually paired bony processes that arise from the head of many ungulates
